Chest Shop is a plugin that allows you to buy and sell items from a chest. Players can buy your items at any time from these chests even if you are offline. You may also sell items to shops that specify so on the chest signs as long as the owner has enough money for the interaction. Funds will be added or subtracted from your balance automatically in both cases.
